SPECIFICATION forming part of Letters Patent No. 391,656, dated October 23, 1.889.

Application filed March 15, 1888. Serial No. 267,255.

- TaaZZ whom it may concern:

Be it known that 1, CHARLES GRAM SMITH, a citizen of the United States, residing at 329 Massachusetts avenue, Washington, in .the District of Columbia, have invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to improvements in buttons for boots, shoes, gloves, carriage-curtains, and other artic1es,wherein said buttons are made automatically adjustable, so as to avoid the inconvenience now experienced of having to shift the position of the buttons when the shoes, gloves, and. other articles do not fit; and by my invention the use of a button-hook is dispensed with, my improved button being readily fastened with the fingers, whether the fit of the article be tight or loose. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure l is a top view of an adjustable button embodying my invention. Fig. 2 is a top view of a glove-button constructed according to my invention. Fig. 3 is an enlarged side elevation of Fig. 1. Fig. 4 is a top View of the lower or stationary plate. Fig. 5 is avertical section of Fig. 4 on line x :r. Fig. 6 is an under side view of a modification of my invention. Fig. 7 is a central vertical section on line to w of Fig. 6, the two plates being separated.

The same letters of reference apply to the same parts in all the figures.

My invention consists, essentially, of two plates pivotally connected together, the lower plate being securely fastened in any suitable manner to the fabric upon which it is to be used, and the upper plate pivotally connected thereto in such a manner as to be capable of being locked in any required position by antomatic devices.

In the drawings, A represents the upper movable plate slotted concentrically from a to b and from the latter point (b) radially and outwardly to the outer edge of the plate, so as to form a tongue, B. The free end of said tongueB is bent downwardly, so as to form an elastic or spring pawl capable of engaging in (No model.)

the ratchet-teeth of the lower plate, hereinafter described.

0 is an arm extending outwardly from the plate A, and has a shank-button, cl, of any approved construction or material securely fastened to its outer end. Plate A is centrally g hole, h, to receive thelower reduced end, i, of

pivotal stud e.

In Fig. 6 the lower plate is shown provided with serrations j on its edge in lieu of the face ratchet-teeth g of Fig. 4.

The under side of plate A, Fig. 7, is provided with a springpawl, 70, whose outer free end is adapted to engage with said serrations j of plate 0.

For carriage-curtains, or wherever my im proved button is to be secured to wood or other framework, the pivotal stud c is lengthened below the lower plate and screw'threaded, as shown at Z, Fig. 8.

Plates A and 0, after being constructed as hereinbefore described, are pivotally secured together by means of pivotal stud e by rivet ing its reduced lower portion, z, to the lower plate, as shown in Fig. 6, or by riveting its upper end, m, when lengthened into a screw or bolt, as shown in Fig. 3.

It will be seen from the above that my improved device when used on shoes, gloves, 820., will enable the wearer to tighten or loosen the same, as desired.

The springpawi can be turned only in one of my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. An adjustable button-fastener consisting of an upper revoluble plate provided eecen- 1 plates united bya centralstud and adapted to IO trieally with a shank-button and having a rotate one upon the other and to be locked in spring-pawl integral with the same, in colnbiany desired position by means of a ratchetnation with a lower stationary plate provided wheel and a spring-pawl, as herein set forth.

with a circular-faced ratchet-Wheel and a central pivotal stud, as herein described, and for CHARLES. SMITH the purpose set forth. XVitnesses:

2. As an improved article of manufacture, J As. W. DYRE, the button herein described, composed of two E. N. \VATERS.
